The aim of the present study is to evaluate the influence of the healing abutment height on secondary implant stability measured by resonance frequency analysis. In this prospective observational clinical study of 30 implants, the secondary stability of the implant was measured via resonance frequency analysis of the abutment during the osseointegration process. Two groups were compared: a <4 group ( = 15), with a space between the healing abutment and the antagonist of <4 mm, and a ≥4 group ( = 15), with a space of ≥4 mm. Statistically significant differences ( < 0.05) in the implant stability values obtained at surgery (T0) and at the eighth week of osseointegration (T8) were observed between the two groups, with higher values for the <4 group. Pearson's correlation analysis revealed a trend towards a significant relationship with the mean force (-0.6546) and a linear inverse relationship, so that by decreasing the distance between the abutment and the contact with the antagonist, the secondary implant stability values increased. A comparison of the mesial and distal peri-implant marginal bone levels at T0 and T8 did not reveal statistically significant differences ( > 0.05). A greater healing abutment height, placing it closer to the antagonist, increases and accelerates secondary stability, as measured by resonance frequency analysis. The results of the study support the recommendation of using high healing abutments, placing the abutment close to the opposing occlusal plane, according to biomechanical criteria.
本研究的目的是评估愈合基台高度对通过共振频率分析测量的种植体二级稳定性的影响。在这项对30颗种植体进行的前瞻性观察性临床研究中，在骨结合过程中通过对基台进行共振频率分析来测量种植体的二级稳定性。比较了两组：<4组（n = 15），愈合基台与对颌牙之间的间隙<4 mm；≥4组（n = 15），间隙≥4 mm。两组在手术时（T0）和骨结合第8周（T8）获得的种植体稳定性值存在统计学显著差异（P < 0.05），<4组的值更高。Pearson相关分析显示与平均力有显著关系的趋势（-0.6546）以及线性反比关系，即通过减小基台与对颌牙接触之间的距离，种植体二级稳定性值增加。T0和T8时种植体近中和远中边缘骨水平的比较未显示统计学显著差异（P > 0.05）。如通过共振频率分析所测量的，更大的愈合基台高度，使其更靠近对颌牙，会增加并加速二级稳定性。研究结果支持根据生物力学标准使用高愈合基台并将基台放置在靠近对颌咬合平面的建议。
